  • RE : how can one re-install windows 10 after the free upgrade?

    If the Windows 10 that you had installed was also activated, you have a digital license saved at the server.

    The digital license allows you to reinstall the SAME Windows 10 edition into the SAME computer anytime you want and as often as you want.
    No product key is required, and activation will be automatic because the server will recognize the digital license and activate the installation automatically.

    Use the following Media Creation Tool to download the ISO files of your edition of Windows 10.
    https://www.microsoft.com/en-ca/software-download/windows10

    Click the Download Tool Now button and Run it.
    Make sure you select the same edition, language and bit-version your Windows 10 is using.
    Then select Create installation media for another PC
    That will begin downloading the ISO file to your computer.
    When download is completed, you have 2 options:

    1. Do an In-place Upgrade Install:
    RIGHT click at the ISO > click Mount > click Setup.exe ( or Setup.)
    That will begin installing Windows 10.
    You have the choice of keeping settings, files and apps, or keeping nothing.
    No product key is required.
    Activation will be automatic (as explained above.)

    2. Do a Clean Install:
    Burn the downloaded iso files to a bootable media (DVD or USB), and use it todo a clean install.
    Clean Install do not allow you to keep anything. So, you need to back up files you want to keep. You will have to reinstall all the apps you have installed.

    RE : How can one get the product key for an old version of Office which is currently installed on the laptop

    There are keyfinders in the web you can install. It will find your Office product key. Such as ..........
    Magical Jelly Bean Keyfinder , Show Key Plus. Just to name two.
    I personally recommend those 2 because I have used them and they work.
    Do that before you reinstall Windows 10 and write down the key number for safe keeping.

    RE : Will the user files be affected?
    If you do an in-place upgrade install (the method posted above), you can keep your files, settings and apps. They will not be affected.

    If you do a Clean Install, all your files, settings and apps will be deleted. You start fresh.

  • Hi ,

    david hk129 has provided very detailed information, I cannot agree more. Please allow me to add one more point. Yes, if you upgraded to Windows 10 before July 29th, 2016, you will be able to install and activate the same edition of Windows 10. Because it will generate a Windows 10 key to activate your system after upgrading. In fact, there is a tool could be used to backup Windows 10 key. I think it might be useful for you. I will post here.

  • I plan on upgrading several hardware components ( main board, processor and memory). What happens, if Windows 10 does not work properly anymore after the hardware was replaced and I need to do a clean re-installation? Will Windows 10 recognize, that this is still my old computer or will it think I try to install windows on an additional computer and therefore block me from installing it? As far as I know, each license is associated with a hardware footprint. As long as this footprint ist the same there is no issue but once components get replaced it can get difficult. Thanks.

  • For those asking how to get Product Keys from old versio of Office, or if you need to extract your current Windows Key.

    Try ProduKey. Small simple effective.

    Still works on Windows 10, obviously can't extract Office 365 as it's tied to your MS account.
